How do I go on after trying dungeons hundreds of times?

probably one that has cleared coil T1-T5 this way they should have no issues with Moggle

Wut? You don't need to clear coil period to even clear Mog or Titan HM. I cleared it just fine on my first relic. Took a day of serious practice but beats it in the end :/ And that was a month and a half after release 10/6/13.
OP, if you have no time to PF or no friends to ask to come, I'm sorry but you won't get a clear before your break.
